d aspartic acid

It's suppose to aid in muscle growth and recovery by increase of growth hormones and test.  Could some nutrition guru's chime in?  And what's this i hear about it also increasing estrogen while it increases test?  and therefore you would need an aromatase blocker along with it if you're goign to take it.

confused.

what you've heard/read is probably voodoo. you probably get all the aspartic acid you need from your diet. any supplemental probably has at best a small effect. and i hate to break it to you, but the people for whom this (and lots of other boutique dietary supplements) might have an actual training effect are light years ahead of you or me or most of the dudes on here.

only abstract i could find, which doesn't exactly inspire confidence:

Abstract
BACKGROUND:

D-aspartic acid is an amino acid present in neuroendocrine tissues of invertebrates and vertebrates, including rats and humans. Here we investigated the effect of this amino acid on the release of LH and testosterone in the serum of humans and rats. Furthermore, we investigated the role of D-aspartate in the synthesis of LH and testosterone in the pituitary and testes of rats, and the molecular mechanisms by which this amino acid triggers its action.
METHODS:

For humans: A group of 23 men were given a daily dose of D-aspartate (DADAVIT) for 12 days, whereas another group of 20 men were given a placebo. For rats: A group of 10 rats drank a solution of either 20 mM D-aspartate or a placebo for 12 days. Then LH and testosterone accumulation was determined in the serum and D-aspartate accumulation in tissues. The effects of D-aspartate on the synthesis of LH and testosterone were gauged on isolated rat pituitary and Leydig cells. Tissues were incubated with D-aspartate, and then the concentration (synthesis) of LH and cGMP in the pituitary and of testosterone and cAMP in the Leydig cells was determined.
RESULTS:

In humans and rats, sodium D-aspartate induces an enhancement of LH and testosterone release. In the rat pituitary, sodium D-aspartate increases the release and synthesis of LH through the involvement of cGMP as a second messenger, whereas in rat testis Leydig cells, it increases the synthesis and release of testosterone and cAMP is implicated as second messenger. In the pituitary and in testes D-Asp is synthesized by a D-aspartate racemase which convert L-Asp into D-Asp. The pituitary and testes possesses a high capacity to trapping circulating D-Asp from hexogen or endogen sources.
CONCLUSION:

D-aspartic acid is a physiological amino acid occurring principally in the pituitary gland and testes and has a role in the regulation of the release and synthesis of LH and testosterone in humans and rats.

That statement seems positive.

in·duce 
/inˈd(y)o͞os/
Verb

    Succeed in persuading or influencing (someone) to do something.
    Bring about or give rise to: "measures that induced a change".

1. To make greater, as in value, beauty, or effectiveness; augment.
2. To provide with improved, advanced, or sophisticated features: computer software enhanced with cutting-edge functionalities.

in other words, d aspartic acid brings about a rise and makes of greater value GH and testosterone release.  So, d aspartic acid aids in muscle recovery.

So faster recovery aids in faster gains

So faster gains aids in higher vertical

So higher vertical aids in dunking on ppl

When i dunk on ppl i get more confidence

when i get more confidence, that chick that is a 9/10 that i've been trying to get with in the last 12 months might start to get with the program.

so it is not just so, it is SERIOUS business.
